Demonstrates 2D topological phases and propagating edge states in space-time photonic crystals, including an exponentially growing edge state along the space-time interface.
In a 1D Su-Schrieffer-Heeger model augmented by exponentially decaying long-range interactions, increasing the interaction range triggers topological phase transitions even for weak coupling strengths.
